Excellent pics — Thank you. From what I'm gathering with your photos, and some other research, is that your seat is actually not a stock GB500 single-seat. It is definitely a stock GB400 seat judging from the original mounting hinge and the functioning latch, but I feel like it could've been a single or dual. The 500 single-seat has a much larger hollow area underneath the hump. This area is so deep that it covers a larger frame-mounted tool box and is impossible to flatten out and re-shape into a dual-seat or shallow hump single-seat. (which is the problem I have) The 400 seat has a much shallower hollow area. This area appears to hold a small strap-on tool bag in it's underside that has some sort of pop-off lid. This area appears shallow enough to be re-shaped for a dual-seat or shallow hump single-seat. (what you have) Now I just need to find a pan like yours and I can re-shape... thanks for the help.

anglia4, I'm in downtown manhattan... city riding not so much, but being able to get out of town is the whole point! twisties upstate. Yes, I've seen the original dual seat... don't like the clunky rear so much. Definitely looking for shape more streamlined like the nice reupholstered one. Thanks for the other link, will look in to it. Would still love to see a photo with that seat on the bike if possible....... ?

duke, congrats on the build. i really like the style of seat you show in the photo when you got it back from the upholsterer. do you have any pics of that seat on the bike? i love my original single seat w/hump on my gb500, but looking to have an optional seat that can sit two-up, while still looking good when i'm on it solo. would love to see shots of the construction, angles, and underside of the seat as well as on the bike. it's a lot to ask i know! any info is appreciated. thanks in advance.

crispymk2, congrats on the bike... here in the U.S. the 400 doesn't exist so it's nice to see one looking good. q: is that the way the original seat looks on that or where did you get that? my gb500 has a taller hump that is hollow underneath. it looks amazing, but it doesn't allow me to ride my gf on the back. yours looks like it might sit two-up if necessary? would love to see a top or top angle view. would also love to see the underside. at least just for reference on how i might fabricate a seat that can sit two-up, but still look sporty when one person is on it. thanks in advance.
